What I'm concerned about is that the UB900 does tone mapping, whereas the ATV 4k does not AFAIK
Or does tone mapping only apply when I want to convert HDR to SDR?
Which I don't, because the JVC will have settings appropriate to HDR.
I used to have a UB900 & Vertex. I used the Vertex to trick the UB900 into sending SDR BT2020 to my JVC RS400 projector. I sold the UB900 & Vertex and got a UB820, it is significantly better. No hyperbole, it is worth every single penny. I have the recommended settings here for JVC/UB820 owners
I know it isn't what you want to hear but the UB900 is not the best player to use, the UB820 has significant
advantages over the UB900, namely: HDR Optimizer and SDR2020 without needing an HD Fury device.
A small caveat: The ATV sometimes does weird things to the JVC RSx00 projectors, which sometimes required a HD Fury Vertex (or a Linker or Integral...I forget which) to remedy. I do not know if that affects the RS420, likely not.
Don't get too hung up on "HDR". Your projector can't really do it anyway and the UB820 (and to a lesser extent the UB900 when tricked with the HD Fury) decodes the HDR signal and still sends a full range signal to your projector, but it simply recognizes it as SDR since it's already been tone-mapped.
I've been where you are, if you stick with the UB900 you will be seriously missing out. The UB900 still holds good value so upgrading to the UB820 isn't that much more. Buy the UB820 and discover what your projector is truly capable of. You can thank me later.
